Following error returns when attempt to use printf in hub-side template configmap name. 

2023-11-23T23:53:02Z    ERROR    controllers.ClusterGroupUpgrade    Policy is invalid    {"error": "(printf \"ztp-site-%s\" .ManagedClusterName): printf variable is not supported in the template function Name field"}


In 4.15, an option siteConfigMap is added to ZTP siteconfig in order to auto-generate site-specific configmap later used by hub-side templating - since every site will be generating configmap with different name, unable to dynamically compose the configmap name in PGT essentially makes this new addition unusable in scale. 

 4.15

    100%

    1. use siteConfigMap to auto generate configmap that will be used by hub-side templating later on. configmap name is: ztp-site-{sitename}
    2. in PGT, use hub-side template to where configmap name is dynamically composed e.g., 

deviceType: '{{hub fromConfigMap "ztp-group" (printf "ztp-site-%s" .ManagedClusterName) "sriov-device-type" hub}}'
    
    3. attempt to apply the templated policy via TALM
    

    error returned by TALM:
